The PRS price lists show squabbin uncovered 57/08 as follows:
2015: Custom 22, P22 & P24
2014: P22 & P24
2013: Custom 24, P22
Pretty sure any P series guitar thats not a single cut had them before the latest refresh that put 85/15s in them.
I suppose that part of my confusion was that I thought they weren't putting 57/08's in guitars during that time frame. My 2011 CU24 came with 59/09's and I thought that was all you could get at that time because that is what came "stock". Basically, I thought the 57/08's had been discontinued (for lack of a better word) once the 59/09's had come out. I also knew that PRS was very protective of their 57/08's and that you couldn't just buy them OTC which further led to my confusion.
